Specification of Letters Patent. Patented Sept. 23, 1919.

Application tiled May 13, 1918. Serial No. 234,287.

To all whom t may concern.'

Be it known that I, GEORGE IV. PETER, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful In'iprovement in Stoves, of which the following is a specification.

This invention relates to improvements in oil heaters for use principally although not exclusively in heating refrigerator and vegetable cars in winter time. The primary object of this invention is to provide a portable heater which can easily be placed in or removed from a car and when so placed and adjusted is not liable to get out of adjustment by the motion, jolting and vibration of the car, and which is not liable to become broken by objects striking against the adjusting mechanism.

I/Vth these and other objects in View, my invention comprises the features of construction and combination of parts hereinafter particularly described and claimed.

In the accompanying drawing forming part of this specilication, Figure 1 is a front elevation of my invention; Fig. 2 is a plan, and Fig. 8 is an enlarged sectional view of a detail taken on the line X-X of Fig. 1.

In the drawing let A indicate the body of the heater which is formed with the annular` compartment B or reservoir in which the liquid fuel such as kerosene oil is placed and from which said fuel flows downwardly through a duct 2 into the lower portion of the annular wick chamber C. This wick chamber contains a Wick holder 3 by which the wick et is held, said wick holder being provided with a rack 5 with which the teeth of a pinion 6 on the inner end of the shaft 7 coperate, so that by turning the shaft 7 by the use of a handle 8 on its outer end, the wick is raised and lowered to adjust the size of the flame at the upper end of the wick chamber. Air is admitted to the flame through the openings 9 in the lower portion of the body and passes upwardly around the wick. Suitable burner tips 10 surround the upper end of the wick to regulate the flame and a chimney D is detachably mounted over the burner tips through which the heated air and products of combustion pass into the car to be heated. A heater of the kind described used for heating cars is usually subjected to rough handling by articles being knocked about the car when loadin unloadlng or in transit, and there is like ihood of the adjustingmechanism for raising and lowering the wick being changed in position and. of becoming broken by articles striking against the parts. To avoid these objections the shaft 7 is journaled in aI supporting member 11 projecting rigidly from the side of the wick receptacle C and the periphery of the handle 8 is formed with a plurality of notches or grooves 12 into one of which the spring pressed pin 13 projects and holds the handle from turning. This pin 13 is slidably mounted in a lug 14, which is formed integral on theside of the support 11.. A circular plate 15 near the outer end of the pin 13 is used as a presser piece for pushing the pin 13 out of connection with the handle 12 to permit the handle 12 being turned freely when desired to regulate the height of the wick 4. A helical expansion spring 16 around the body 17 of the pin and interposed between the outer end of the. lug 14 and the push plate 15 exerts an outward pressure and urges the pin back into any one of the notches 12 in the regulating wheel 8. A stop pin 18 in the inner end of the vbody 17 of the pin limits the outward thrust movement of the pin 13. The parts of this regulating mechanism described are all placed within a cavity E formed in the upper portion of the body A of the stove, so that the body of the stove acts as a guard to protect the wick regulating mechanism from injury. This cavity is formed by shaping the walls of the body above the fuel reservoir into any shape convenient for closely surrounding the regulating mechanism to wholly protect the same from receiving any knocks from articles in the car, but at the same time permitting the free operation of the regulating mechanism by hand when desired. In use the push piece 15 is pressedinwardly to remove the lock pin 13 from engagement with the hand wheel 8 and when so disengaged the hand wheel can be turned to regulate the height of the wick 11. Instantly upon releasing the lock pin it is adapted to renter one of the notches 12 and thus hold the hand wheel from turning unintentionally.

In accordance with the patent statutes I have described the principles of operation of my invention, together with the apparatus which I nonT consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth Within the scope of the following claims.

Y' Having described my invention, What I claim'as new and desire to protect by Letters Patent is l. A heater having a burner, a regulator for said burner, said heater having a body formed With a recess in which said regulator is placed to protect the latter.

2. A heater having a body formed with a recess in its side, a burner in said heater and a regulator for said burner placed Wholly Within said recess below the surface of said `body for protection.

3. A heater having a body formed With a recess in its side, a burner in said heater, a regulator for said burner and a lock for releasably holding the regulator adjusted, said regulator and lock being Wholly contained in said recess for protection.

4. A heater having a cylindrical body formed With a radial recess in its upper and side surfaces, a burner in said heater, and a regulator 'for said burner contained Wholly Within andV accessible from aboveV and from the side of said body.

In testimony whereof, I have signed my name to this specification.

GEORGE W. PETER.
